The Unnamed is a copper and gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Workings): Workings / Exploration = Brief reconnaissance mapping and three soil samples collected. Soil samples showed moderate copper and gold anomalies, containing up to 122 ppm Cu and 0.02 ppm Au.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Geology): Geologic Description = Small color anomaly in Unalaska Formation (see Drewes and others, 1961) at granodiorite or diorite intrusive contact. Color anomaly is a zone containing more than 2 percent sulfides (pyrite?) 500 feet (150 m) by 3,000 feet (900 m) in size and elongate to the northwest. A breccia pipe which outcrops on the shore is outside of the iron-stained color anomaly area, but contains some chalcopyrite and has a prominent green stain.
Comment (Deposit): Model Name = Copper porphyry, epithermal gold vein(?)
Comment (Deposit): Model Number = 17, 25
Comment (Exploration): Status = Inactive
